* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($91.1k this quarter). Holder counts are more reliable. Shares outstanding: 37.5m as of 2026-08-06, from the company's own SEC filing; the percentage can still exceed 100%: lent-out shares are counted by the lender and the buyer, and some reports overlap without saying so. Implied quarter-end price ≈ $42.43. Options: 7 managers hold calls ($80.6m notional), 8 hold puts ($27.2m).
